The products made by PE heat shrinkable film manufacturers can be used in many industries. There are many things in the process of use. Now let’s take a closer look at the introduction of this knowledge? When choosing products, because There are many types of it. In order to ensure its quality, some methods can be used to distinguish it. First, the flood identification method can be used. PE heat shrinkable film will float in food containers with qualified water quality, and will sink to the bottom of poor or unqualified food containers. The second is to use sensory recognition methods. The qualified food PE heat shrinkable film is smooth and flexible to the touch, and feels more astringent to the unqualified packaging when it is felt by hand. Finally, it is easy to ignite by using the ignition identification method. The blue flame is toxic and harmful. For example, the unqualified PE heat shrinkable film is not easy to ignite. Next: What are the characteristics of PE heat shrinkable filmPrevious: How to distinguish the quality of PE heat shrinkable film
